  • 0

I”m trying to get web2py running on an Ubuntu machine. All the docs seem to indicate that to run it on a *nix system, you download the source and do:

python web2py.py

I grabbed the source (stable source, not the trunk, version 1.99.4) and tried the above, but after entering a password for the server I get (in the terminal):

$ python web2py.py

And then in the browser I get:

Any suggestions? I’m running Python 2.7.1+. I’ve read elsewhere that you also need pyschopg2 installed for web2py to run, and I’ve confirmed that this is in fact installed as well (I did a sudo apt-get install python-psycopg2 and got “python-psycopg2 is already the newest version”).

    Are you trying to run web2py on appengine environment?

    Do you have SQLITE module working ok in your Python?

    A possibility is permission issue, your user have permission to write to web2py/* folder?
